274 TRANSACTIONS OF THE [1895 
Ardella exilis (191). " Least Bittern. 
Common during summer, this little bird is seldom seen except 
by those who look for it, and owing to the marshes in which it 
lives, not always to be found by those who do. 
On May 12 (’94, Wholey), six were noted in Patapsco 
Marsh, but that they are here earlier is shown by nests contain- 
ing 5, 3 and 1 eggs, respectively, which were noted at the same 
place on May 17 (’93, A. Wolle), and in the last week of Sep- 
tember, 1894, one was brought to A. Wolle, who kept it alive 
for some time in his shop window. The latest date for eggs is 
July 8 (’92), when four nearly fresh were collected at Sparrow’s 
Point. It also possibly occurs more or less regularly on inland 
swamps. In May, 1893, one was caught alive in Dulaney’s 
Valley by Mr. Dukehart. 
Ardea herodias (194). Great Blue Heron. 
Between March 30 (’98, Gray) and November 19 (’90, Resler) 
this species is noted with more or less regularity, but so far I 
have been unable to find a “heronry” in Maryland. 
In winter it has been observed at Back River on December 
7 and 21 (92, Resler). Noted at Hagerstown (Small), and 
Cumberland (Shriver). 
Ardea ‘egretta (196), American Egret. 
Irregular during late summer and early fall, this species has 
been noted from July 5 (82), when one was at Gunpowder 
Falls a short distance below the Belair Road, to September 1 
(93 A. Wolle), when one was at Gunpowder Marsh; on September 
23 (94, Tylor) two were at Ocean City. 
In Dulaney’s Valley, one out of a flock of 9 was shot by Mr. 
Thos. Peerse in front of his house, and another was taken by 
Mr. Dukehart in the fall of 1893. 
Possibly some may nest in Maryland, as “Mr. Wm. Palmer 
has known this species to nest in Arlington Cemetery, Va.”
